Matplotlib.axes.Axes.get_frame_on() in Python

0 0 1 minute read

Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. The Axes Class contains most of the figure elements: Axis, Tick, Line2D, Text, Polygon, etc., and sets the coordinate system. And the instances of Axes supports callbacks through a callbacks attribute.

matplotlib.axes.Axes.get_frame_on() Function

The Axes.get_frame_on() function in axes module of matplotlib library is used to get whether the axes rectangle patch is drawn or not.

Syntax: Axes.get_frame_on(self) Parameters: This method does not accept any parameters. Returns:This method returns whether the axes rectangle patch is drawn or not.

Below examples illustrate the matplotlib.axes.Axes.get_frame_on() function in matplotlib.axes: Example 1:

Python3

# Implementation of matplotlib function
import numpy as np
import matplotlib.pyplot as plt
  
x = np.arange(-5, 5, 0.01)
y1 = -3 * x*x + 10 * x + 10
y2 = 3 * x*x + x
  
fig, ax = plt.subplots()
ax.plot(x, y1, x, y2, color ='black')
ax.fill_between(x, y1, y2, where = y2 >y1, 
               facecolor ='green', alpha = 0.8)
ax.fill_between(x, y1, y2, where = y2 <= y1, 
               facecolor ='black', alpha = 0.8)
 
ax.set_frame_on(False)
x = ax.get_frame_on()
ax.text(-2, 80, "Value of set_frame_on : " +str(x),
        style ='italic', fontsize = 10, color ="green")
ax.set_title('matplotlib.axes.Axes.get_frame_on()\
 Example\n', fontsize = 12, fontweight ='bold')
plt.show()

Output: Example 2:

Python3

# Implementation of matplotlib function
import numpy as np
import matplotlib.pyplot as plt
   
x = np.arange(16)
y = np.sin(x / 3)
   
fig, ax = plt.subplots()
   
ax.step(x, y + 2, label ='pre (default)')
ax.plot(x, y + 2, 'o--', color ='black', alpha = 0.3)
   
ax.step(x, y + 1, where ='mid', label ='mid')
ax.plot(x, y + 1, 'o--', color ='black', alpha = 0.3)
   
ax.step(x, y, where ='post', label ='post')
ax.plot(x, y, 'o--', color ='black', alpha = 0.3)
   
ax.grid(axis ='x', color ='0.95')
 
x = ax.get_frame_on()
ax.text(4, 3.2, "Rectangular Patch is Drawn : " +str(x),
       style ='italic', fontsize = 10, color ="green")
 
ax.set_title('matplotlib.axes.Axes.get_frame_on()\
 Example\n', fontsize = 12, fontweight ='bold')
plt.show()
